We present some modifications of the Hoede-Bakker index defined in a social network in which players may influence each other. Due to influences of the other actors, the final decision of a player may be different from his original inclination. The modifications presented in the paper are defined for an arbitrary probability distribution over all inclination vectors. In particular, they concern...

This paper models the sea port system with the objective of determining the optimal storage strategy and container-handling schedule. It presents an iterative search algorithm that integrates a container transfer model with a container location model in a cyclic fashion to determine both optimal locations and corresponding handling schedule. A genetic algorithm, a tabu search and a tabu search/...

Some years ago Koutras presented a method of constructing a conformal Killing tensor from a pair of orthogonal conformal Killing vectors. When the vector associated with the conformal Killing tensor is a gradient, a Killing tensor (in general irreducible) can then be constructed. In this paper it is shown that the severe restriction of orthogonality is unnecessary and thus it is possible that m...

An efficient disparity estimation algorithm for multi-view video sequences, recorded by a two-dimensional camera array in which the cameras are spaced equidistantly, is presented. Because of the strong geometrical relationship among views, the disparity vectors of a certain view can for most blocks be derived from the disparity vectors of other views. A frame constructed using that idea is call...

1. Introduction. Let Φ = {φ 1 , · · · , φ T } be an iterated function system (IFS) on R d. The attractor E ⊂ R d of Φ is the unique compact set such that E = ∪

A new robust clustering scheme based on fuzzy c-means is proposed and the concept of a fuzzy mega-cluster is introduced in this paper. The fuzzy mega-cluster is conceptually similar to the noise cluster, designed to group outliers in a separate cluster. This proposed scheme, called the mega-clustering algorithm is shown to be robust against outliers. Another interesting property is its ability ...

This thesis introduces a new integrated formalization of the conceptual spaces framework proposed by Gärdenfors. We extend the notion of conceptual space generated by a set of prototypes by adding a weight vector to each prototype. This will allow us to represent non-uniformly scaled concepts and, as a special case, partial concepts. We also present a novel Weighted Prototypes-Based Categorizat...

Container handling problems at the container terminals are NP-hard problems. In this paper, we propose a new handling operation’s design and simulation of empty containers, taking into account the interrelated activities at the container terminal. This simulation have been built using a doubled trailer. It moves containers from quayside to yard side or the opposite depending on the flow in cont...
